Wien (euro adhoc) - May 14, 2009 - C.A.T. oil AG (O2C, ISIN:
AT0000A00Y78), one of the leading providers of oil and gasfield
services in Russia and Kazakhstan, through its operating subsidiary
CATOBNEFT, received an additional sidetrack drilling order for Fiscal
Year 2009 by LUKOIL. The new service assignment is worth about EUR 10
million (assuming a Rouble-to-Euro exchange rate of 48), thereby
increasing C.A.T. oil´s 2009 order book volume to approx. EUR 198
million. The sidetrack drilling jobs will be carried out in the
Kogalym area and will lead to an allocation of two of C.A.T. oil´s
sidetrack drilling rigs to LUKOIL´s well sites in West Siberia,
thereby strengthening C.A.T. oil´s presence in this region.

Manfred Kastner, CEO of C.A.T. oil AG, said: "In light of the
currently chal-lenging market environment we are proud of having
received this additional order by LUKOIL which has been our client
for more than 15 years and is Russia´s largest oil producer. This
contract demonstrates yet again our strong customer relationship, as
well as our operating performance. Thanks to our state of the art
sidetrack drilling rigs with an average age of less than three years
we are able to provide efficient services which are even more
important in economically difficult times. We see our Company well
prepared to work on our 2009 objective which is to increase our
market share in sidetrack drilling in the Russian market to more than
20%."

Over the past few years C.A.T. oil has significantly expanded its
sidetrack drilling capacities from two rigs in 2006 to ten in 2007
and 14 by the end of 2008. Sidetrack drilling has been growth driver
number one in 2008 and sidetrack drilling job counts went up by
165.7% YoY, making C.A.T. oil the fastest growing company in this
business in Russia.

About C.A.T. oil AG:

Austria-based C.A.T. oil AG (O2C, ISIN: AT0000A00Y78) is one of the
leading providers of oil- and gasfield services in Russia and
Kazakhstan. C.A.T. oil´s core business is hydraulic fracturing, a
process which helps to open up oil- and gas-bearing rock formations
in order to increase or even enable oil and gas production. The
C.A.T. oil crews use state-of-the-art methods and technologies to
generate high pressure in the oil or gas reservoirs concerned. This
pressure causes cracks to appear in the rock through which oil or gas
can be produced in larger quantities from the production well, and
hence efficiently boosts extraction, particularly in the case of
deposits that are difficult to develop or low-output wells. In
addition, hydraulic fracturing can be used to revitalize wells that
have previously been idle.

The Company has its headquarters in Vienna and employed 3,621 people
at the end of 2008, most of whom are based in Russia and Kazakhstan.
Customers include leading oil and gas producers such as Gazprom,
KazMunaiGaz, LUKOIL, Rosneft, and TNK-BP. C.A.T. oil has been listed
in the Prime Standard of the Frankfurt Stock Exchange since May 4,
2006, and has been a member of the SDax since September 18, 2006.
